The ui_server proxies WebSocket connections. It was accepting the client's WebSocket connection (ws.onopen triggered on the client), but if it couldn't connect to the backend (or if the backend disconnected), it would drop the client connection right away (ws.onclose triggered).
The issue was that reconnectAttempts was being reset to 0 inside the ws.onopen handler. Because the connection was briefly succeeding before failing, the reconnectAttempts counter was resetting to 0 on every attempt, completely circumventing the exponential backoff mechanism and causing a tight reconnection loop.
Modified the WebSocket logic across all relevant UI components to delay resetting reconnectAttempts = 0. Instead of resetting immediately upon the TCP socket opening, it now safely waits until a valid JSON payload {"type": "connected"} is successfully received from the backend.
The duplicate functions at lines 455-486 were redefining cacheElements and
bindEvents with wrong element IDs (kebab-case vs camelCase in HTML).
This caused 'Cannot read properties of null' error on slides app init.
